The stage 2 lesson is divided into 4 steps:
1. introduction

2. cooperative learning
There are 3 topics:

• Topic 1: sensors

You can choose from:

• 1. Ultra-sound sensor: HCSR04 https://create.arduino.cc/projecthub/microBob/ultra-sonic-ping-sensor-a9c49e
• 2. Temperature sensor: LM35 http://playground.arduino.cc/Main/LM35HigherResolution
• 3. Infrared sensor
• 4. Light dependent resistor (LDR, need 10K resistor)
• 5. Potentiometer/ voltage divider

Tasks:

• 1. Choose at least 3 sensors to study
• 2. Understand how the sensors work
• 3. Connect the sensors to Arduino, build circuits
• 4. Try to use Arduino serial monitor to test the success of installation of the sensors

• Topic 2: Android

Tasks:

• 1. Understand all pins analog/digital & input & output of arduino
• 2. Study how to read Analog input: https://www.arduino.cc/en/Tutorial/AnalogInput
• 3. Study how to use serial port communication between Arduino and PC (python) , you can use one source first, Check in the Arduino serial monitor

• Topic 3: Python end

Tasks:

• 1. Python for reading from serial port
• 2. Study how to Display analog data from Arduino using Python (matplotlib): https://gist.github.com/electronut/d5e5f68c610821e311b0
• 3. Do simulation with generated data, MODIFY to one source first

3. reciprocal learning
You are regrouped to the jigsawed groups for reciprocal learning
make your own group innovation
